The surface of epT.I.P.S. LoRetention is achieved through an innovative treatment at the molecular level: the Pearl Effect Technology. The tips are uncoated and free from additives, thus nothing can bleed into the sample. Liquids roll off completely, so that almost no sample remains in the tip. In comparison, the adhesive layer of liquid in standard tips retains considerably more sample material. This unique material property guarantees maximum sample recovery, improved reproducibility and higher sensitivity.
